How to change truecolor DWG objects to indexed ACI colors?

A - answer DWG drawings containing entities with truecolors can be complicated to process, filter, plot or assign plot styles (e.g. monochrome). Such drawings are e.g. generated from Inventor (saved as a "DWG for AutoCAD").

You can easily recolor such drawings to nearest indexed (ACI) colors from the AutoCAD 256-color palette. Download the SetACIcolor freeware LISP utility from www.cadstudio.cz/download, load it into your AutoCAD with APPLOAD and type the SETACICOLOR command. Select the objects (or All) to convert and this tool will replace all individually colored "truecolor" entities (including those nested in blocks or in locked layers) to the nearest indexed color hue.

Sample - a photo converted to truecolor 2Dsolid DWG "pixels" with ImgConvert and the solids then converted from truecolor to ACI colors:
